Engine Masters Air Cleaner Dyno Testing

Not a dynamic realistic setup.... no engine bay/box, cooling fan, road draft.
Good food for thought.

1. WHY didn't they test the Amsoil air filter elements??? Amsoil is a friggin' sponsor! What does this tell us about the Amsoil elements, that they won't even test the product? Does anyone think this was a simple oversight?

2. WHY didn't they test an air cleaner base without the filter element or top? Everyone knows that a carb alone doesn't make full power without at least an air-cleaner base to smooth the air flow.

3. Loved the salad bowl.

4. Loved the taped-off regular filter, with a filtered lid making more power than the regular filter plus the filtered lid.

5. I wish they'd have shown how badly a typical "carb hat" and cone filter worked.

6. Overall, reasonable info presented in a hateful way. I could use a lot less of the magazine-guy personalities.

Note the carburetor in use for that testing has a smooth contour for the airflow, probably a "HP" series. Important to note a carb design WITHOUT a smooth contour, example one with a choke tower and a Q-jet carb design, will affect the testing results in SOME of those instances.

Also I'd be curious to know how much effect there would be with each type of filtration used with a throttle body and direct port fuel injection. Ant thoughts on that ?

A salad bowl? That makes me think the 77 Camaro at the track with a 90 degree stove pipe bolted to the carb might have been faster than the $500 setup on the car next to it! They would love my setup, a factory air cleaner with rectangles cut out on the back of the unit with a re-useable air filter, feels fast to me!

Steve, depending on the type of throttle body used (assuming a 4 bbl clone deal vs a single blade EFI type part, the airflow numbers should be close to a HP Holley. Airflow might be a bit higher across the board because of the absence
of the Boosters in the air flow channels.

I had posted about this when it first came out. yeah Im sure we can all think of things we would have like to have seen. But I think it still yields numbers worth thinking about in back to back testing. I actually bought one of those B&B units.

Thanks Tom. Mine is a 4150 style from a Holley HP EFI Universal MPI Retrofit Kit.

That's what I was thinking. I was surprised at the affects with the smooth HP main body entrance, so I can only imagine the bigger hit it would take using a carb with a choke horn.

How about the Stub Stack?

I used it (when carbed) and helped.
(no air cleaner though)

I remember those. Not heard of much anymore but a test would be interesting. I remember them being made for both Q-jet and 4150 carbs. I believe at one time there were complete air cleaner bases that incorporated that stub stack design as well, all one piece. Always wondered how well those worked.

That's pretty close, also looks like a pretty serious drop. The one I remember was a flatter base, with sort of a stub stack molded into it. Might of been K&N at the time making those but I'm not sure.

One of their best episodes

[Steve C.]

Regarding the Stub Stack. When I talked with K&N Tech they supported the fact that it makes the entrance similar to a Holley 'HP' series carburetor. It is this smooth contour that helps work with the K&N X-Stream lid. Whereas apparently a carb design without a smooth contour (example with a choke tower) and like a Q-jet carb doesn't work well with a X-Stream lid.

"I believe at one time there were complete air cleaner bases that incorporated that stub stack design as well, all one piece. Always wondered how well those worked."

Testing of the K&N Flow Control air cleaner assembly can be found here if interested:

That's the base I was thinking of. Thanks Steve.

Nice looking piece, all formed around the choke tower. I always thought these were interesting, just never tried one.
